Sept. 29 is National Coffee Day. A day to celebrate a drink that many people can’t start their day without. There were numerous stores, like Dunkin’ Donuts, who had given out free or discounted coffee on this day, but when you got your cup o’ Joe, did you know the interesting facts about coffee:

1.) A dancing goat discovered coffee. Well, farmers in Ethiopia noticed that their goats would get all jumpy after eating coffee beans, so they decided to try it for themselves.
